Supertex inc. HV2761 Low Charge Injection, 24-Channel, High Voltage Analog Switch with Bleed Resistors Features General Description Applications Input data is shifted into a 24-bit shift register that can then be retained in a 24-bit latch. To reduce any possible clock feed through noise, the latch enable (LE) should be left high until all bits are clocked in. Data are clocked in during the rising edge of the clock. Using HVCMOS technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► 24-channel high voltage analog switch Integrated bleed resistors on the outputs 3.3 or 5.0V CMOS input logic level 3:1 MUX-deMUX with 8 states 20MHz data shift clock frequency HVCMOS technology for high performance Very low quiescent power dissipation,10µA Low parasitic capacitance DC to 50MHz analog signal frequency -60dB typical OFF-isolation at 5.0MHz CMOS logic circuitry for low power Excellent noise immunity Cascadable serial data register with latches Flexible operating supply voltages Medical ultrasound imaging Piezoelectric transducer drivers Inkjet printer heads Optical MEMS modules The Supertex HV2761 is a low charge injection, 24-channel, high voltage analog switch integrated circuit (IC) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as medical ultrasound imaging, piezoelectric transducer drivers, and printers. The bleed resistors eliminate voltage built up on capacitive loads such as piezoelectric transducers. The device is suitable for various combinations of high voltage supplies, e.g., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V.

When LE is low the shift registers data flow through the latch. 4. DOUT is high when data in the register 23 is high. 5. Shift registers clocking has no effect on the switch states if LE is high. 6.
